Answer 1

Answer:

[tex](x,f(x)) = (-1,8)[/tex] -- Another point

[tex]a = 8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = a|x|[/tex]

[tex](x,f(x)) = (1,8)[/tex]

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in [tex]f(x) = a|x|[/tex]

[tex]8 = a|1|[/tex]

Remove absolute bracket

[tex]8 = a*1[/tex]

[tex]8 = a[/tex]

[tex]a = 8[/tex]

Substitute 8 for a in [tex]f(x) = a|x|[/tex]

[tex]f(x) = 8|x|[/tex]

Let x = -1

[tex]f(x) = 8|-1|[/tex]

Remove absolute bracket

[tex]f(x) = 8*1[/tex]

[tex]f(x) = 8[/tex]

So, another point is:

[tex](x,f(x)) = (-1,8)[/tex]

Solving (b): The value of a

This has been solved in (a) above

[tex]a = 8[/tex]

What is a mathematical expression?

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Quantities (operands), factors, operations, operations, braces, grammar, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's sequence of operations and other features. In algebra, a value may be designated by an expression; this value may rely on the values given to the variables that the expression contains. The semantics associated with the symbols in the expression determine this value. The expression's context determines which semantics to use. Depending on the suggested sequence of operations by the context, the identical syntactic statement 1 + 2 3 might have multiple values (mathematically 7, but also 9).

The given expression is 3.4.(6+12)

And it can be solved as

3.4.(6+12) = 12.18 = 216

Hence, the value of the above expression is 216.

Answers

Answer:

The answer is 26

Step-by-step explanation:

All we do is multiply 4/8 by 52.

find the image of ( 1 , 2 ) after a reflection about y = x followed by a reflection about y = - x

PLS ONLY ANSWER IF YOU KNOW THE ANSWER.

Answers

the answer should be the following:
1. (2,1)
2. (-1,-2)

Answer:

(-1,-2)

Step-by-step explanation:

Think of the line y=x as a mirror.  The image of the point (1,2) is obtained by drawing a line through (1,2) perpendicular to the line y=x and finding the point on the perpendicular line that is equal distance from the line y=x but on the other side. This gets you to the point (2,1).

Similarly, from (2,1) find the mirror image using the line y=-x as the mirror. You travel diagonally 1.5 diagonal squares to reach y=-x and then continue another 1.5 diagonals to reach (-1,-2) which is your answer.

A more accurate value is roughly 512.575960394824

==============================================================

Explanation:

With many trig problems, a diagram should help steer you in the right direction. See below.

The red angle is the angle of depression. It's formed by starting off looking straight horizontal, then we look down 26 degrees. The blue angle adds to the red angle to get 90, so we can see that 26+64 = 90. Or you could say 90-26 = 64.

The goal is to find the value of x, which is the length from B (the lighthouse base) to point C (the ship's location).

The lighthouse is 250 ft tall, meaning AB = 250

We'll use angle BAC, or angle A for short, as the reference angle. This is the blue angle in the diagram.

We have a known adjacent side (AB = 250) and an unknown opposite side (BC = x). We use a tangent ratio to tie these sides together with the reference angle in question. This way we can solve for x.

-------------------

tan(angle) = opposite/adjacent

tan(A) = BC/AB

tan(64) = x/250

250*tan(64) = x

x = 250*tan(64)

x = 512.575960394824

x = 513

The distance from B to C is roughly 513 feet.

A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected

To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli with mean weight of 15.26 grams and standard deviation of 2.56 grams. The margin of error (ME) to construct a 99% confidence interval for the true mean amount of cheese filling is

A) 2.064 B) 1.432 C) 3.745 D) 1.276 E) 1.797

b. A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected

from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli and measure the weight of cheese filling. They find the 99% confidence interval of 14.16 to 15.84 grams. Which of the following is the correct interpretation?

I. We are 99% confident that the mean weight of cheese filling in all ravioli made by this process is between 14.16 and 15.84 grams.

II. 99% of all ravioli made by this process will have cheese filling weights between 14.16 and 15.84 grams.

III.We are 99% confident that the interval (14.16, 15.84) contains the mean weight of cheese filling in all ravioli made by this process.

IV. The weight of cheese filling in the ravioli is between 14.16 and 15.84 grams 99% of the time.

A) I only

B) III only

C)I and III.

D) II and III

E) I and IV

Answers

Answer: a. B) 1.432

              b. E) I and IV

Step-by-step explanation:

a. Margin of error to construct a 99% confidence interval is calculated as

[tex]ME=t.\frac{s}{\sqrt{n}}[/tex]

where

t is the critical value expressed as t-score, which comes from t-distribution;

s is sample standard deviation

n is sample size

In this case, a t-score is used because the population standard deviation is unknown and the sample size is small, n < 30.

The way to find t-score is:

1) Define the degree of freedom, which is sample size minus 1: df = n - 1;

2) Compute alpha: [tex]\alpha=1-\frac{confidence}{100}[/tex];

3) Find the critical probability: [tex]p=1-\frac{\alpha}{2}[/tex]

With the df and critical probability, consulte the t-distribution table and find the score.

For the cheese filling:

df = 24

p = 0.995

t-score = 2.797

Calculating margin of error:

[tex]ME=2.797.\frac{2.56}{\sqrt{5}}[/tex]

ME = 1.432

The margin of error to construct a 99% confidence interval for the true mean amount of cheese filling is 1.432.

b. Confidence interval is an interval in which we have a percentage of certainty that the true population mean is. For example, with a 99% confidence interval of 14.16 to 15.84 grams, we are 99% confident that the true mean weight of cheese filling is between those numbers or that the weight of cheese filling is between 14.16 and 15.84 grams 99% of the time.

Answer:

The price of hot dog is $2.5 and that of a pretzel is $1.25.

Step-by-step explanation:

Let the cost of hotdogs be x and that of pretzels be x.

So,

4x+3y = 13.75 ...(1)

and

2x+5y = 11.25 ...(2)

Multiply equation (2) by 2.

4x+10y = 22.5 ...(3)

Subtract equation (1) from (3).

4x+10y-(4x+3y) = 22.5-13.75

4x+10y-4x-3y = 8.75

7y = 8.75

y = 1.25

Put the value of y in equation (1).

4x+3(1.25) = 13.75

4x+3.75 = 13.75

4x = 13.75-3.75

4x = 10

x = 2.5

So, the price of hot dog is $2.5 and that of a pretzel is $1.25.

What is the area of this figure?

Answers

9514 1404 393

Answer:

  54 square units

Step-by-step explanation:

One way to find the area is to divide the figure into 3 parts using a horizontal line at y=3.

The trapezoid below the line has bases 9 and 7, and height 6, so an area of ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(9 +7)(6) = 48 . . . . square units

The left triangle above the line has a base of 3 and a height of 2, so an area of ...

  A = (1/2)bh

  A = (1/2)(3)(2) = 3 . . . . square units

The right triangle above the line has a base of 6 and a height of 1, so an area of ...

  A = (1/2)(6)(1) = 3 . . . . square units

Then the total area is ...

  figure area = trapezoid area + left triangle area + right triangle area

  figure area = (48 + 3 + 3) square units = 54 square units
